Dusk to Dawn vs. Motion Detection

Dusk-to-dawn flood lights come on when the sun sets in the evening, and they stay on all night, or until their internal battery charge is depleted. They are an excellent option if you want to illuminate your property with continuous light. The downside of dawn-to-dusk solar lights is if the previous day was overcast or rainy, their batteries may not charge to maximum capacity. If this happens, the Flood Light may stay on only a few hours before it dims and goes out. Motion-detection flood lights turn on only when they sense motion, and they remain on for a predetermined amount of time, usually 20 to 30 seconds, before turning back off. Because motion-detection lighting uses less battery power, it is more likely to function all night long.
